3M 7100008178 Hot Melt Adhesive Clear 5/8 X 8 Inches

Product Description

The 3M 7100008178 is a clear, 100% solids thermoplastic hot melt adhesive in a 5/8-inch x 8-inch stick format. Sold individually, this adhesive is designed for use in compatible hot melt glue applicators and delivers a fast-setting, strong bond across a wide range of substrates. It offers good impact resistance and maintains flexibility at low temperatures, making it suitable for applications where thermal cycling or cold-environment performance is a factor. The adhesive is particularly noted for bonding to difficult plastics, including polyolefins, which are often resistant to standard adhesives. Installers and assembly technicians working in HVAC, electrical, or light manufacturing environments will find this a reliable general-purpose bonding solution.

This hot melt adhesive is suited for both residential and light commercial applications where a fast, clean bond is needed without mixing or curing time. Typical use cases include securing wire harnesses, bonding plastic components, sealing, and general assembly tasks. Its clear finish makes it appropriate for visible or semi-visible joints where aesthetics matter. It bonds to many plastics, wood, fabric, and similar porous and semi-porous materials, making it a versatile option across multiple trades.

Key Features

• Clear, 100% solids thermoplastic formula leaves no residue or clouding at bond line
• Bonds to many plastics including polyolefins, which resist most standard adhesives
• Good impact resistance maintains joint integrity under stress or vibration
• Flexible at low temperatures, suitable for cold-environment installs
• Fast-setting hot melt format — no mixing, no cure time, ready immediately after cooling
• 5/8-inch diameter stick fits standard hot melt applicators designed for that bore size

Compatibility

Designed for use with hot melt glue applicators that accept 5/8-inch diameter adhesive sticks. Consult the manufacturer applicator guide for a full list of compatible dispensing equipment.

Installation Notes

Allow the applicator to reach full operating temperature before dispensing to ensure proper flow and adhesion. Keep the work surface clean and dry before applying adhesive, as contamination reduces bond strength. Allow the applied bead to cool and set fully before applying load to the joint. Follow all applicator manufacturer guidelines for safe handling of hot melt equipment, as dispensed adhesive exits at elevated temperatures and can cause burns.
